Yes, KLocale was in many ways the best localization library around, I
and others worked hard to make it that good, but ultimately it's one
that lost because it made KDE a walled garden and failed to play well

ubiquitous mess that is the industry standard. Sometimes you just have
to take a stepp backwards in order to be able to move forward.

People are free to liberate it from kdelibs4support and embed it
themselves, but it's a lot to ship and maintain, and at the end of the
day you end up with localization that doesn't match what the rest of
the system does.

The roadmap was waiting on two things: me to get motivated to work on
Option 3 after burning out on the first two rejected options, and for
Qt to drop Windows XP/Vista support. We can't get new Locale stuff
into Qt that only works on a couple of platforms, it has to work on
every platform from day 1 with some lowest common denominator of
features, and Windows XP was so pathetic we couldn't do much more with
it than QLocale already does. With XP/Vista gone, we can target a more
useful feature set. But even once all that is implemented, I still
have to convince Lars and Thiago to accept it :-)

I've recently been trying to update the plan at for those interested, it
provides a lot of background detail about what we want to do and why
it has been so hard to achieve. Frankly, 18 months ago I had been
looking for sponsorship to implement all this as it is a massive
undertaking, but it's one of those things everyone wants to just work
but no-one is interested in paying to be done right.
